Gastric Neuroendocrine Tumor [PDF]

open access: yesThe Surgery Journal, 2021
AbstractGastric neuroendocrine tumor (gNET) is a rare carcinoid of the stomach whose incidence is increasing due to widespread use of upper gastrointestinal endoscopy (UGIE). There are four types of gNETs with different management strategies and prognosis. Here, we present a patient who came with abdomen pain and intermittent melena.

Renal neuroendocrine tumors

open access: yesIndian Journal of Urology, 2009
Neuroendocrine tumors (NETs) are uncommon tumors that exhibit a wide range of neuroendocrine differentiation and biological behavior. Primary NETs of the kidney, including carcinoid tumor, small cell carcinoma (SCC), and large cell neuroendocrine carcinoma (LCNEC) are exceedingly rare.The clinicopathologic features of renal NETs diagnosed at a single ...

Neuroendocrine tumors of the gallbladder (Review)

open access: yesOncology Letters, 2020
A gallbladder neuroendocrine neoplasm (GB-NEN) is a unique heterogeneous neoplasm, originating from neuroendocrine cells and able to secrete peptides as its neurotransmitter. Among all the neuroendocrine tumors (NETs), the GB-NEN prevalence is 0.5%, which accounts for ~2.1% of all gallbladder tumors.

Neuroendocrine tumors of the prostate [PDF]

open access: yesModern Pathology, 2018
Neuroendocrine (NE) differentiation in tumors of the prostate or in the setting of prostate cancer (PCa) is rare. A survey of these lesions is presented, including usual PCa with focal NE marker-positive cells, Paneth cell-like change, prostatic 'carcinoid', high-grade NE carcinoma, as well as other tumors that do not fit neatly into these categories ...

Neuroendocrine Tumor Markers

open access: yesFrontiers in Neuroendocrinology, 2001
Tumor markers used in the diagnosis and follow-up of patients with neuroendocrine tumors are in most instances not specific for a given tumor and circulate under normal conditions in the serum, making their use as an early diagnostic tool difficult (low sensitivity).

Plasma acylated and plasma unacylated ghrelin: useful new biomarkers in patients with neuroendocrine tumors?

open access: yesEndocrine Connections, 2016
To date, the value of fasting plasma acylated ghrelin (AG) and unacylated ghrelin (UAG) as potential novel biomarkers in patients with neuroendocrine tumors (NETs) is unknown.The aims of this study are to (i) compare fasting AG and UAG levels between ...

Gastroenteropancreatic Neuroendocrine Tumors

open access: yesCa, 2018
Neuroendocrine tumors (NETs) are heterogeneous malignancies arising from the diffuse neuroendocrine system. They frequently originate in the gastroenteropancreatic (GEP) tract and the bronchopulmonary tree, and their incidence has steadily increased in ...

Epidemiologic trends of and factors associated with overall survival in patients with neuroendocrine tumors over the last two decades in the USA

open access: yesEndocrine Connections, 2023
Background: Updated epidemiological data of neuroendocrine tumors are currently lacking. Thus, we performed epidemiological and survival analyses on a large cohort of patients with neuroendocrine tumors and developed a new nomogram to predict survival.
